Be itknown that I, AUGUST Tmssn, a citizen of the United States,residing at Chi cago. in the county of Cook and State of Illinois. haveinvented a new and useful Improvement in Pasteuriz ng Apparatus, ofwhich the following is ti-specification.

My object is to rovide is construction of pasteurizer by which thepasteurizing op-. eration may be carried on-continuously, and underpressure when'desired, whether the pasteurizing agent bestea'm or water,and

by which pasteurization of the material to uniformly.

to 55 inclusive which are likewise spaced equidistant'fromeach other andcommunicate, respectively, with the interior. of the receptacles 16 to24 inclusive at their righthand endsin F g. 2, when the receptacles areinthepositions illustrated in Fig. 1;

In the particular construction illustrated,

the head 31 contains seven angle-shaped conduits 56 to 62 inclusivewhich open through its periphery and its outer face as repre sented ofthose conduits illustrated in Fig. 2, the conduits 56 to 62 inclusivebeing so arranged that when the receptacles occupy the positionsrepresented in Fig. 2 they will communicate with the conduits 10 to 16inclusive, respectively. The conduits 56 to 62 inclusive communicatewith pipes 63 to 68 inclusive and an exhaust-pipe 69, respectively, thepipes 63, 64 and 65 leading into the lower ends of tanks 72, 71 and 70,re-' spectively, and the pipes 66, 67 and 68 containing pumps 73 areadapted to discharge into the tanks 70,, 71 and 72 respectively,

- these tanks being designed. to receive water for circulation throughthe receptacles 16 to 24. inclusive as hereinafter described, andmaintain it at different degrees of temperature for producing gradualheating of the material to be pasteurized, pasteurization of the sameand subsequent cooling thereof, as for-instance the water in tank 72 maybe maintained at 18 R, that in tank 71\at 35 R. and that in tank 70 at48 1%., though it will be understood from the following descriptionofthe operation of the apparatus that the temperature of the water inthe different tanks may be varied as conditions require The head 32contains four passages 74, 75, 76 and 77, which are 'sodisbottles,'-cans orthe like,' 'c'ontaining the mar. terialto be pasteurized arerepresented at.

'7 9,-these supports preferably being m'ade'of-v posed as to cause theconduits.-18, 49, 50 and 51 to communicate with the conduits 5 5, 5 1,53 and 52, respectively, when the receptacles occupy the positionsillustrated-1 in Fig; 2 for effecting circulation therethrough of thepasteurizing water as hereinafter described.

It will be notedfrom the foregoing that thestationary heads 31 and 32form with their cooperating sleeves 34; and 35, respectively, valves forthe conduits at the opposite en s of the receptacles for controllintheflow of water from the several tanks into. and out of the latterwhen-the rings 25 are intermittently rotated andthe, receptacles carriedthereby niove. in a circular path.

Each receptacle l6to 24 inclusive is provided-at its opposite end with aswinging door 78,1.which, when closed, renders the rcceptaclefluid-tight. The supports forthe wire fabric in the form-.ofibasketsprovided on "their under sides with rollers ,dQ- which rest onythe inner"surfaces oftlie receptacles-1- and b .taine which the supports arealways main less of the positions occupied by the receptacles during theoperation of the apparatus as hereinafter described.

W hen the gear 84 in its' rotation meshes with thegear 83 the receptacles are' caused to travel in a circular path to theleft in F1 1 a (118 'tance equal to one-ninth of the clrcumfera once ofthe circle n whiclrthey l'1e,'t o cause all of the receptacles to bemoved one-mnth of a revolution in the direction indicated by the arrowin'Fig. 1. 'lhe 'e fi'iect of thus operating the apparatus is toci'iuse' receptacle l7'to be moved into-the position occupied byreceptacle 16 in' Fig. 1 and advanrre each of the other receptacles tothe positions" formerly occupied bythe next receptacle in As the heads31 and 32 are stationaryand the sleeves 34 and 35 rotate with thercceptacles,tthe operation of the latteras described destroys ,the.couunuuicatrons bctween'the receptacles descrihei'l when lIl'tl'lGposit-ions illustrated ll] Fig. l and' 'establish -s new comuuiuicatimisbetween the several receptacles asis manifest from the drawii'igs. Thereceptacle 17 having been emptied-ofthe water contained therein bydrainingit-into thereccptacle 16, it is now in a position-t0 permit ofthe removal of the pasteurizin'g material and the introduc-v tiontherein of raw material to be. asteur-' ized zt-he-water'iu receptacle18 (raining sis.'during-this.operation into receptacle/16. It.

will be noted that by the time the receptacles have made a completerotationby theinter- -1nittent action referred to, the materialstituting for it raw material, is being performed in the receptacles asthey successively occupy the position representcdof casing 16 in Fig. 1,the material in the other receptacles is being subjected to the waterfrom'the tanks 70, 71 and 72, and thus the operation of the pasteurizeris rendered continuous. The parts of the drive mechanisms -for thereceptacles may be so proportioned as to provide as long periods ofrest, during drawing the pasteurized material, and su'bwhich the'pasteurizing fluid is'actingupou.

the material, as desired.-

To insure the discharge of thewater from the several receptacles theysuccesslvely occupy the position represented of recepta ole 17 in Fig.1, 1 provide on each receptiv cle a vacuum .valve 200 which operates ina. well known manner to permit air to enter the receptacles when theinternal pressure is less than that of the atmosphere. 7

While I prefer toemploy a plurality of. tanks for furnishing water tothe receptacles .at different temperatures and to -provide nine of thereceptacles for the material to be pasteurized, I do notwishto beunderstood v as intending to limit my invention'toil is feature of theconstruction, as the number of receptacles may be increased ordiminished as desired, and likewisc'the number-of tanks, in some casesthe use of water at pasteurizing temperature only being desirable.

In 'Figs. 10 to.13 inclusive, I have illustrated my invention asapplicable to the use i of steam as the pasteurizing fluid.- In thisconstruction, in which the parts corresponding to those shown in thepreceding figures are designated by the same numerals, the

head 86, which corresponds to the head 31 of the preceding figures,dili'ers therefrom 1n the particular of having nine right-angledconduits 87 to 96 inclusive instead of.

the seven provided in the head 31', the sleeve 97 cooperating therewithand corresponding to the sleeve 34,- and the head 98 and sleeve 99corresponding to thehead 32 and sleeve 35, respectively, being of thesame jconstrucion and provided with the same conduits and passages asillustrated and described of thesimilar parts 34', 32 and 35,respectively,

of the-preceding figures, excepting that the head 98 contains a port 201which registers with the passage 47 when the receptacles occupy thepositions represented in' Fig. 10

and is adapted to register successively with the passages 48 to 55inclusive as the receptacles are advanced in their circular path ofmovement, as hereinafter described. In this construction, the conduits87 to 96 inclusive communicate with ipe's 100 to.108 inclusive,respectively, the ipes 101 to,104 inclusive communicating with" asteam-supply pipe 109; the pipes 105 to 108 inclusive'communicatin withareturn steam-pipe 110, and

the pipe 100 serving asan exhaust, the pipes 109 and 110 being connectedwith any suitable source of steam-supply for introducing steam into thepipes 101 to 101 inclusive,

. thence through the conduits 88 to 91 inclusive and through theconduits 39 to 12 inclu sive, thence through the receptacles 17 to 20inclusive, and from these receptacles through the receptacles-21 to24c-inclusive communi eating therewith through the medium of the 20valve formed of the parts 98 and 99 as described of the constructionillustrated in the preceding figures. Steam courses through the variousreceptacles containing the mate rial to bepasteurized at alltimes,excepting when such receptacles successively occupy the positionpccupiedby receptacle 16 in Fig. 10, in which position its steam conduits areclosed to the steamsupply and communication is made between it and theexhaust-pipe .100 which enables the steam to escape from the receptacleto place it n a condition in 'which its pasteurized contents may-beremoved and raw material for pasteurization may be substituted. It isreferred that the conduits for each receptac e leading into the valveformed oi the parts 96 and 87 open into a pipe terminating in a ,hollowringshaped' pipe 111, having a section thereof broken away to affordoppositely directed openings 112 which, when the receptacles area at thelowermost point reached bythem in their movement in a circular path,extend :close tojthe bottom of the receptacles and serve {to permit ofthe withdrawahunder thepressure of the outgoing steam of the waterofcondensation collected therein.

The receptacles of this construction may bedriven as described of thereceptacles in the preceding figures, to cause them tosuccessively-assume the position represented of receptacle 16 in Fig. 10to permit-of the removal therefrom of the pasteurized material and thesubstitution therefor of material to be pasteurized. The 'port 201communicates with a pipe 202 whichleads to any suitable source ofcompressed air supply whereby when the receptacles successively assumethe position represented of receptacle 16 in Fig. 10, the steam will beforced there-- from through the exhaust-pipe 100.

A modification of the receptacles of the construction shown in Figs.'lto 11 inclusive is. represented in Figs; 14 and 15. .In this case, thereceptacles instead of remaining in fixed, position and inverting asthey move through a circular path, arepivotaii y sup ported to causethem to remain upright at all times, a description of the particularconstruction illustrated being as follows: The arms 36 and 37 areprovided toward their outer ends with transversely-extending bearings113 in which tubular extensions 11a carried by receptacles 115to123inclusive are journaled, these tubular extensions comniunicating withdownwardly-extending conduits 124: in the receptacles, and theseconduits opening into the interior of the latter. The receptacles 115 to123 inclusive are door-controlled at" their ends -as described thatuniform pasteurization may be effected.

It will furthermore be noted that by pro:.

viding a plurality of receptacles adapted to be maintained, =during thepasteurizing operation inair-tight condition,- the pasteurizing mediummay be circulated or passed therethrough under any pressure desired,which is of especial advantage in the case of pasteurization of beer inbottles, in which case theincreased pressure exerted by the gases formedin the bottles may be compensated for to equalize the strain on thelatter and thus prevent breakage from this cause.
